MANY therapists/counselors specialize in Dual diagnosis.. so let's say you have a patient with opiate abuse and they maintain dx of bipolar or anxiety.. The service is coded by the actual "MEAT" of the therapy and the focus of the therapy. So if a patient has a history of abuse/addiction of opiates, they may receive counseling for substance abuse with secondary dx (dual dx).

IT depends ON THe services the provider is rendering.. if they are rendering psychotherapy with the primary dx of a mental health issue it should be coded appropriately as psychotherapy. If your provider is rendering a group session for alcohol/drug .. it's coded appropriately with the appropriate dx code for alcohol and substance abuse.

I have clients who do BOTH.. they should be clearly documented in the chart. You also don't want to bill BOTH for same date of service as most carriers will NOT pay for two sessions in one day.

That would be H0015 : Alcohol And/Or Drug Services; Intensive Outpatient (Treatment Program That Operates At Least 3 Hours/Day And At Least 3 Days/Week And Is Based On An Individualized Treatment Plan), Including Assessment, Counseling; Crisis Intervention, And Activity Therapies Or Education
